摘　　要：目的比较杀虫剂高效氯氟氰菊酯微囊悬浮剂和顺式氯氰菊酯悬浮剂对野外蜱虫的杀灭效果,探索一种高效稳定长期有效的蜱虫控制新方法,便于在蜱传疾病暴发流行和应急状态时快速降低蜱虫密度。方法选择蜱虫侵害率较高的野外自然环境,划定100 m^(2)规模的3块区域,2处作为试验区,1处作为对照区,杀灭前用布旗法对3块划定区域的蜱虫密度进行本底调查,之后,用普通喷雾器对试验区现场进行杀虫剂滞留喷洒,开展蜱虫杀灭效果试验。结果在药物喷洒1 d后试验区游离蜱密度为0,14 d时现场复核,喷洒顺式氯氰菊酯悬浮剂的试验区监测到蜱虫,而喷洒高效氯氟氰菊酯微囊悬浮剂的试验区42 d后仍未监测到游离蜱,表明高效氯氟氰菊酯微囊悬浮剂杀灭蜱虫持效期更长。结论卫生杀虫剂可快速降低游离蜱密度,高效氯氟氰菊酯微囊悬浮剂具有较好的灭蜱效果,灭蜱持效性更佳。Objective To compare and test the efficacy of lambda⁃cyhalothrin microcapsule suspension and alpha⁃cypermethrin suspension concentrate against ticks in the field,and to explore a new method of efficient,stable and long⁃term effective tick control,so as to rapidly reduce the tick density during the outbreak of tick⁃borne diseases and emergency situations.Methods The natural field environment with high tick infestation rate was selected,and 3 areas with a scale of 100 m^(2) were designated,2 were used as test areas and 1 was used as control areas.The tick density in the 3 designated areas was investigated with the flag method before killing.After the background investigation,insecticide was applied to the test area with a common sprayer to carry out tick killing effect test.Results The density of free ticks in the test area was 0 after 1 day of drug spraying,and ticks were detected in the test area sprayed with cypermethrin after 14 days,while no free ticks were detected in the test area sprayed with alpha⁃cypermethrin after 42 days.The results showed that lambda⁃cyhalothrin had a longer duration of killing ticks.Conclusion Hygienic insecticides can rapidly reduce the density of free ticks,and lambda⁃cyhalothrin has better tick killing effect and longer killing duration.
